Profile cannot be accessed

more options

Hello!

I'm getting an error message from Firefox whenever I try to open it that my profile is missing or cannot be accessed (see attached image).

I have tried everything from the help articles so far, and nothing worked. I deleted the profiles.ini file, I deleted the entire Firefox folder under Application Support, I have deleted Firefox and reinstalled it. None of that worked.

Even when I try to create/delete/save my profile over the Terminal, I get the attached error message.

I love using Firefox, but I simply cannot use it this way. No matter if I use the default, developers or nightly version.

If anyone has an idea how I could fix the issue I would be incredibly thankful.

Thank you already in advance for your help!

Maybe check the read/write permissions and owner for both locations used for the profile folder.

Location used for the main profile that keeps your personal data (Root Directory on about:profiles).

  • ~/Library/Application Support/Firefox/Profiles/<profile>

Location used for the disk cache and other temporary files (Local Directory on about:profiles).

  • ~/Library/Caches/Firefox/Profiles/<profile>

I will keep this in mind for the next time the problem occurs. Today, after downloading Firefox again, it worked without any problem.
